This is not true you could get mingw and learn c++ after you learn a
command line compiler you can use any c++ compiler in fact you can use the
express at the command line now.

To the original poster, what compiler are you using? Wish I could get
visual
studio 2010 express to work with jfw, but apparently not, so I can't even
start learning c++.

How are you printing?
The old way of printing was to move 9 to AH, or was it AL,.. god I don't'
remember. But it was an int 21
Take care,
Sina

Hi Everyone,
Is there someone who can help me on this little simple problem?
I am sure that my main problem is that I do not understand how the
registers and storage areas work.
The following is a simple console program. It adds two numbers entered
by
the user. and displays the answer. My problem is when the anser is > then
9
I have tried adding the two numbers to eax and displaying from eax, and
moving the numbers to ah, al and adding the two numbers, all I display is
garbage.
I hate to bother you with this such a small problem, but I really do not
understand why I cannot display what is in register eax.
I will greatly appreciate anyone's help on this.
Thank you,
Celia
// reads the first digit then clears the buffer
loop10:
lea ecx,b;
call putstr;
call getch;
cmp eax,'0';
je loop10
sub eax, '0';
mov x, eax;
call getch;
// reads the second digit
lea ecx,b;
call putstr;
call getch;
sub eax,'0';
mov y, eax;
mov ebx,x;
mov ecx,y;
add eax,ebx;
add eax,ecx;
// this part does work when adding two numbers < 10
add ecx,ebx;
//cmp eax , '10';
add eax,'0';
add ecx,'0';
call putch;
}0;//return 0;
}
